This week cyclist Tyler Hamilton joins us on Sports Coach Radio. Once Lance Armstrong’s most-trusted lieutenant, Tyler went on to become one of his biggest rivals and then one of his most devastating adversaries.

Tyler has experienced the greatest highest and deepest lows in professional cycling: a Tour de France stage victory, an Olympic Gold medal and huge winnings. And then suspended twice for using illegal drugs, stripped of titles and shunned by his peers. He was one of the first riders of his generation to be punished for cheating, but certainly not the last.

Sports Coach Radio is hosted by Glenn Whitney, a coaching and leadership psychologist. You can follow us on Twitter, where we post useful articles and coaching tips just about every day of the week. The handle is @sportscoachtalk. And we’d be grateful if you’d leave a short review of the show on the Apple iTunes page.

Tyler is now coaching mostly amateur riders via his company Tyler Hamilton Training. We caught up with him recently over the telephone from his base in Missoula, Montana.
